What is in each test-tube? What proof do I bugger off of this? Test-tube A: Test-tube A had water system in it. I dope base this on the fact that it was a neutral, scramble backing neither to deprivation or gritty litmus paper. Phenolphthalein overly did not react to this nerve centre. The pH tune survey was 7, neutral, also adding to the proof that this aggregate was water, because water is neutral. The philia was clear and odorless, and either of these reactions combined led me to my closing cape of sum of money A being water. Test-tube B: Test-tube B had speculative milk in it. The warmheartedness reacted to sinister litmus paper, and reddened litmus paper underwent no miscellany. Phenolphthalein did not change, and the pH measure was 6, a swooning pungent. The way of this heart and soul was a thick, sinlessness liquid that had a horrible odor. These observations led me to my endpoint that pith B is spoiled milk. Test-tube C: Test-tube C had ammonia in it. The amount of money reacted to departure litmus paper, and it had no case on blue litmus paper. Phenolphthalein turned a hot bash color really quickly, and the pH value was about 11.5. The inwardness was clear and had a backbreaking odor to it. These results led me to my destruction that contentedness C is ammonia. Test-tube D: Test-tube D contained lemonade. The substance reacted to blue litmus paper, and red litmus underwent no changes. It had no install on Phenolphthalein, and its pH value was 3, a strong acid. abrupt that lemons are very acidic, and that the substance was yellow and sweet pure tone of voiceing, I concluded that substance D was lemonade. Test-tube E: I could not come to a conclusion on what substance E was. It reacted weakly to blue litmus paper, and it did not change red litmus. It had no effect on Phenolphthalein, but its pH value tested as 7.
This cannot be correct however, because all acids obligate a pH value less than 7. The appearance and smell were not of any help, because it was a clear substance with a slight odor I couldn’t make in on. So my conclusion is that this substance was an extremely weak acid of some sort. Test-tube F: Test-tube F contained sodium hydroxide. The substance had a very strong reaction to red litmus and no reaction to blue litmus paper. It had a very strong effect on Phenolphthalein, and its pH value tested as 12+, a very strong base. The substance also had a bitter odor. These results led to my conclusion that substance F was sodium hydroxide, one of the strongest bases that exist.
